Definitions
- the deformation correction coefficient was set assuming that the deformation amount of the side frame and the upper and lower molds was proportional to the magnitude of the force applied to the work.
- the deformation correction coefficient is changed in each case according to the types of the upper and lower molds and the combination thereof. There is a problem in the improvement of workability. Also, for example, if a phenomenon occurs in which the lower end of the upper die bites into the work (refer to the first example, page 6, left column, lines 4 to 5), the amount of deformation is increased. Even if the bending correction is performed while maintaining the assumption that the pressure and the pressing force are simply proportional, there is a problem in improving the bending accuracy.
